Donald Trump's $15 million renovation of the Lincoln Memorial reflecting pool swiftly managed to turn it green, and the president is blaming vandals.

In the Daily Show monologue above, Josh Johnson plays back-to-back clips of Trump accusing someone of cutting the pool with a knife, before showing a clip from two months earlier in which he said such an act was impossible: "I don't want to give anybody any ideas. If you had a knife, you couldn't even cut it," Trump said.

"I've never seen someone have a line of logic so stupid they reverse-Inception themselves," says Johnson. "Me from before had the idea to never. I told myself it couldn't be done, and then I forgot. That's why it happened.

"Look, I'll admit right now I'm one of Trump's biggest haters. But Donnie, let me help you out: You have got to chill. People are not shanking the pool at night. Also, algae can't be that hard to get rid of. I mean damn, you got one of the biggest algae eaters in your cabinet."
